Prof.Dr. Halim Yanikomeroglu, our guest from Carleton University, Canada, gave a series of day-long seminars at our department on July 24th, 2013. Numerous audience from several universities and institutions attended to the meeting.
The seminar's details are below.

We would like to thank Prof. Yanikomeroglu for his valuable talk.

Despite the recent advances in wireless technologies, the wireless community faces the challenge of enabling a further traffic increase of up to 1,000 times in the next 10 years or so, while no customer is willing to pay more for the wireless pipe itself: the so called "traffic-revenue decoupling". Moreover, many experts warn that the low-hanging fruits in wireless research (especially in information theory, communications theory, and signal processing) have already been collected. While the research community is full of ideas (as usual), many of these idea are either not-too-relevant (i.e., not in the bottleneck areas) or they are in areas in which progress toward a tangible implementation is too slow.

In the first part of this seminar (morning session), the following topics will be covered:
   * Fundamental dynamics of cellular communications
* 3GPP operation
* Key technologies in LTE and LTE-Advanced
* Emerging challenges and opportunities in beyond-2020 wireless networks
* Bottleneck problems in beyond- 2020 wireless networks

In the second part of the seminar (afternoon session), 17 potential research directions towards coping with the bottleneck problems, especially in the context of radio access network (RAN), resource allocation, layers 1, 2, and 3, will be discussed, the underlying mathematical tools will also be highlighted:
   D1:  Thoughts on 5G PHY
D2: Non-Coherent Communications
D3: Terminal Relaying
D4: Quality of Experience (QoE)
D5: New Frontiers in Resource Allocation
D6: Steerable Beamforming at the Terminal + Resource Allocation
D7: Novel Channel Estimation and Prediction Algorithms
D8: Uplink Distributed Multi-Channel Multiple-Access in Cellular
D9: Traffic Models
D10: Intercell Load Coordination (ICLC) for Non-Uniform Traffic
D11: Interdisciplinary Approaches in Decision Making
D12: Cell Switching Off in Dense Small Cell Deployment
D13: Robustness in Algorithm and Protocol Design
D14: Layer 8 ? User-in-the-Loop (Demand Shaping in Space and Time)
D15: Millimeter Wave Communications
D16: Advanced Antenna Technologies
D17: Very Small Cell Deployment: Attocells

In the absence of a clear technology roadmap towards 5G, the seminar has, to a certain extent, an exploratory view point to stimulate further thinking and creativity. We are certainly at the dawn of a new era in wireless research and innovation, the next twenty years will be very interesting.
